PROBLEM TO BE SOLVED: To enable prevention of power loss by eliminating the occurrence of a leakage current occurring due to a diode for cutting off an overcurrent caused by static electricity. SOLUTION: A camera module 11 of the I2C communication method includes a lens section 111, an image sensor section 112 for receiving power supply from a power supply line and converting video from the lens section into an electrical signal, and linked to an I2C bus having a serial clock line (SCL) and a serial data line (SDA), a first diode and a second diode 113a, 113b for cutting off the overcurrent caused by discharge of static electricity to prevent the overcurrent from being transferred from the image sensor section to each of the SCL and the SDA, and a first switch and a second switch 20a, 20b for cutting off the linkage of the image sensor section and each of the SCL and the SDA.
